What the answer to this equation be?
scoray [572]

If you expand the square, you have

\dfrac{1}{4}x^2-3x=7x+8-10x

Simplify the right hand side:

\dfrac{1}{4}x^2-3x=-3x+8

Cancel the -3x appearing on both sides:

\dfrac{1}{4}x^2=8

Multiply both sides by 4:

x^2=32

Consider the square root of both terms (using the doubles sign):

x=\pm\sqrt{32}=\pm4\sqrt{2}

A rectangular plot of ground is 30 meters longer than it is wide. its area is 10,000 square meters.
dimulka [17.4K]
A = W· L
10,000 = W ( W +30 ) = W² + 30 W
W² + 30 W - 10,000 = 0
W = \frac{-30+ \sqrt{900+40000} }{2}=  \frac{-30+202.24}{2} = 86.12
L = 86.12 + 30 = 116.12
Width of a plot is 86.12 m and lenght is 116.12 m.
Check : A = 116.12 · 86.12 ≈ 10,000

14 kg of apples cost $154.how much would 16kg cost
ankoles [38]
We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.
